Commodity prices sit near the beginning of many supply chains. Crude oil becomes gasoline, diesel, plastics, and chemicals. Wheat becomes flour and bread. Copper goes into electrical equipment, construction materials, vehicles, and machinery. Natural gas can be used to generate electricity, heat buildings, and manufacture fertilizers.

When the prices of these commodities change, the effects can travel through the economy. Producers may face higher or lower costs for materials and energy. Transport companies can see fuel costs change. Food processors pay different prices for agricultural inputs. Manufacturers may spend more on metals, chemicals, packaging, or other materials.

But a higher commodity price does not automatically translate into an equal increase in the price paid by consumers. Commodity prices are one component of a much larger cost structure, and the strength and speed of the effect depend on the product, industry, market, and country.

Recent movements illustrate how quickly these underlying costs can change. The World Bank's commodity price data, published on October 2, 2026, showed its energy price index rising 25.7% in September, while its food price index increased 3.8%. These indexes track movements in international commodity prices rather than the prices consumers pay in stores.

Businesses combine labor, materials, energy, services, equipment, and capital to produce goods and services. Commodities frequently appear among the material and energy inputs used in that process.

The U.S. Bureau of Labor Statistics provides a useful way to see the difference across industries. Its productivity data divide production inputs into five categories known as KLEMS, covering capital, labor, energy, materials, and services.

Using a five-year average covering 2019 through 2023, BLS found that materials represented 31.2% of manufacturing inputs. By comparison, materials accounted for 10.8% of inputs across its aggregate services category. Labor represented 27.2% of manufacturing inputs but 55.1% of service-sector inputs.

That difference matters. A manufacturer using large quantities of steel, aluminum, copper, agricultural products, or petrochemical materials can be more directly exposed to changes in commodity markets than a labor-intensive professional service business.

BLS also produces input price indexes designed specifically to measure changes in the prices industries pay for goods and services used in production. Its experimental satellite indexes combine Producer Price Index data for domestically produced inputs with Import Price Index data for imported inputs. They exclude labor and capital investment.

These measures help show how price pressure can begin well before a finished product reaches a consumer.

The journey from a commodity market to a retail price is rarely one-for-one.

A business facing higher material costs has several choices. It may raise its selling price, accept a smaller profit margin, reduce other costs, change suppliers, alter the product, or delay a price adjustment. Competition and customer demand can limit its ability to charge more.

BLS notes that factors including competition, profit margins, and the substitutability or necessity of a product influence how production-cost changes are ultimately passed to buyers.

The importance of the commodity within the final product also matters. A sharp increase in the price of a raw material can have a large effect when that material accounts for much of the product's cost. Its effect can be considerably smaller when processing, labor, transportation, rent, marketing, and other expenses dominate the final price.

This is why a 20% increase in a commodity price should not be interpreted as evidence that a related consumer product will also become 20% more expensive.

Energy provides one of the clearest examples of commodity-price transmission because petroleum products are closely connected to crude oil markets.

The U.S. Energy Information Administration divides the retail price of gasoline into four broad components. These are the cost of crude oil, refining costs and profits, distribution and marketing costs and profits, and taxes. EIA describes crude oil as the largest component of the retail gasoline price, although its share changes over time.

Diesel has a similar cost structure. Its retail price incorporates crude oil, refinery processing, distribution and marketing, retail operations, and taxes.

This helps explain why changes in oil markets can become visible at fuel stations comparatively quickly. It also illustrates why retail fuel prices do not move perfectly with crude oil. Refining conditions, distribution costs, taxes, local competition, and profit margins also matter.

Energy costs can then spread further through the economy because businesses use fuel and electricity to produce and transport goods. The European Central Bank, for example, incorporates indirect energy effects into its inflation analysis through production costs such as utilities, intermediate inputs, and transport.

The influence therefore extends beyond the fuel purchased directly by households.

Agricultural commodities provide another important example, but the relationship between farm prices and consumer food prices is more complicated.

A loaf of bread does not consist economically of wheat alone. The retail price also reflects milling, manufacturing, packaging, transportation, wholesale and retail operations, labor, property costs, and other parts of the supply chain.

The U.S. Department of Agriculture's Economic Research Service estimates that farms received 11.8 cents of every dollar spent on domestically produced food in 2024. The remaining 88.2 cents represented the marketing share, covering post-farm activities such as processing, transporting, and selling food.

This does not mean agricultural commodity prices are unimportant. It means their influence is diluted by the many additional costs between the farm and the consumer.

The effect also differs substantially depending on where food is purchased. USDA estimated that farms received 18.5 cents of each 2024 dollar spent on domestically produced food at home, compared with 7.1 cents for food away from home. Restaurants and other food-service establishments have larger marketing shares because preparing and serving meals adds more economic activity beyond the underlying agricultural products.

These figures come from USDA's Food Dollar model, which traces the value of food production through domestic supply chains. The agency comprehensively revised the model and its source data in 2026, so results from the updated model should not be treated as directly comparable with figures published under the previous methodology.

International evidence also shows that different commodities reach consumers at different speeds.

A 2026 IMF working paper examined the transmission of international gasoline, diesel, wheat, and rice prices into domestic retail prices across many countries. The researchers used more than 30,000 pairs of international and domestic monthly prices dating from 2000 and estimated the relationship using a dynamic local-projection model.

The study found that average pass-through was incomplete for both fuel and food, but fuel generally passed through more quickly than food.

For gasoline and diesel, the study estimated that roughly one-third of an international price shock was reflected in domestic retail prices immediately. The estimated average effect reached about 0.8 dollars for every one-dollar international price change after three months.

Food took longer. The estimated peak response for wheat occurred after more than ten months, while the size and timing of the effect varied for rice. The researchers also found substantial differences across countries because domestic pricing systems, subsidies, taxes, market structures, and other policies can alter the connection between international and retail prices.

The study is an IMF working paper rather than an official IMF policy position, and its estimates are averages derived from historical data. They should not be interpreted as fixed rules applying to every country or every commodity-price movement.

Commodity exposure also varies sharply outside energy and food.

Metals such as copper, aluminum, iron ore, and steel-related raw materials feed into manufacturing and construction supply chains. Their prices can influence the cost of electrical equipment, vehicles, machinery, buildings, packaging, and many other goods.

Again, the final effect depends on how much of the finished product's cost comes from materials.

BLS data show why manufacturing can be especially sensitive. Materials represented an average 31.2% of manufacturing inputs from 2019 through 2023, compared with 10.8% in its aggregate services category. Construction was even more material-intensive in the same data, with materials representing 36.0% of inputs.

This does not mean a given percentage increase in metals prices will produce the same percentage increase in manufactured-goods or construction prices. Manufacturers and contractors buy many different inputs, often under different purchasing arrangements, and final prices also reflect labor, capital, services, competition, and margins.

It does mean that commodity markets can materially alter the cost base of industries that consume large quantities of physical inputs.

Commodity prices generally have a less direct influence on many services because labor often represents a much larger share of their costs.

Across the broad services category examined by BLS, labor accounted for 55.1% of inputs on average from 2019 through 2023, while energy accounted for 1.4% and materials for 10.8%. The composition was different in transportation and warehousing, where energy represented 8.4% of inputs and labor represented 42.8%.

A consultancy, for example, is unlikely to respond to copper prices in the same way as an electrical-equipment manufacturer. A transportation company, however, can be much more exposed to fuel prices.

Services can also encounter commodity costs indirectly. Higher fuel costs can affect transportation expenses. Changes in electricity or natural-gas costs can affect the expense of operating buildings and equipment. Rising food costs can affect restaurants and catering businesses.

Commodity prices therefore influence parts of the service economy, but usually through a more complex chain than they do for commodity-intensive goods.

The relationship also works in reverse, but not always symmetrically.

Lower commodity prices can reduce business costs, yet consumer prices may fall slowly or not at all if other expenses continue rising. Labor, rent, insurance, financing, processing, transportation, and other costs do not necessarily decline when a commodity becomes cheaper.

The 2026 IMF study of international fuel and food markets found evidence that price increases were generally passed through more quickly than decreases. Its results suggest that domestic prices can respond differently depending on the direction of the international price movement.

BLS analysis of U.S. manufacturing provides another illustration of why final prices can remain elevated after material pressures ease. During the period following the pandemic, some materials price indexes began falling in 2022 while labor costs and prices for trade services continued rising. The combination of falling and rising input costs meant that final prices reflected more than the movement in raw materials alone.

This is an important distinction between lower inflation and lower prices. If falling commodity costs merely slow the rate at which final prices rise, the price level can remain higher than before.

Commodity markets provide an early view of cost pressures moving through parts of the economy. Rising oil can affect fuel and transport. Agricultural prices can influence food production. Metals can change manufacturing and construction costs. Energy prices can reach a wide range of businesses through utilities and distribution.

But commodity prices do not determine consumer prices on their own.

The final price of a product or service reflects an entire chain of costs and market decisions, including labor, processing, transportation, energy, rent, taxes, competition, productivity, and profit margins. The importance of each factor varies widely from one industry to another.

That is why commodity prices are best understood as one of the forces shaping the cost of goods and services rather than a direct measure of what consumers will eventually pay. When commodities become more expensive, they create cost pressure. How much of that pressure reaches the customer depends on everything that happens between the raw material and the final sale.
